FileMaker Server 17 (version 22.214.171.124)
Windows Server 2016
WebDirect, when set up in a one machine configuration, serves up the launch center ok, but when entering a file, returns a blank page.
Added a worker machine and it works. Turn off worker machine, and the master then redirects traffic to the reported "Host Name" of the master machine, which is incorrectly reported as the Computer Name in windows.
